I want to know how the variables or tags stored in all of these protocol and the different between them. To design a common database for storing the variables of these 4 PLC in MongoDB using node.js.
The only solution is that you get the specifications of each of the protocols, but you will not find those of Siemens S7 due Siemens never published it and those of Ethernet/IP can only be obtained if you are a member of odva.org
To start here you will find Omron FINS specs: https://www.myomron.com/downloads/1.Manuals/Networks/W227E12_FINS_Commands_Reference_Manual.pdf

What do the letters ANT in ANT+ mean.
I understand the logic but not the "acronym", where do the words come from.
Reference: ANT+ (built on the base ANT protocol) defines device profiles that specify data formats, channel parameters and network keys. ANT+ is an interoperable wireless transfer capability that can be used with the basic ANT protocol.
Thanks
According to Garmin training materials it stands for "Adaptive
Network Topology".
Is there a protocol which point-of-sale machine use to talk to a credit card machine? What is the recommended software/hardware platform to prototype a point of sale system?
There are several protocols available, here are some of then: First there is OPI, Open Payment Initiative, specified by Wincor Nixdorf. It is in wide use. Then there is the german ZVT protocol or the Swiss VEZ protocol. It really depends in which region you plan to use it, the protocols I listed definitel are in widespread use in Europe.
It would be easier to get the sdk of your payment gateway and integrate it into you software. I have hooked ip VeriFone, Clover and Priority machines. Each vendor has multiple APIs in different languages.
I'm working on the AFC (automatic fare collection) system which required a SAM( secure access module) for key management.system works fine with local key management in MCU and I don't have any experience in using SAM.SAM required to install beside MCU as main reader controller & contactless card reader chip(PCD).
Is used protocol based on the smart card ISO7816?Am i true?
As i know SAMs are part of SMART cards family,are a SAM javacard or there are javacard SAM and non javacard SAM?
is there upper level standard used for communicating with SAMs(based on iso7816 ) or each manufacturer use its own protocol?
whats different between SAM and usual GSM SIM-CARD? and can i use a GSM-SIMCARD instead of SAM?
is there any standard use case for process of key management in smart cards ?
wbr
A SAM may be a smart card or another chip like a trusted platform module. A TPM is addressed using an API, see here.
SAMs are seldom required, so there are no domain independent standards how to address these.
If a smart card is used, then 7816 is obviously the way to go. A native smart card is also perfectly possible as SAM, especially if Perform Security Operation command of ISO 7816-8 is supported.
A typical SAM command is "encrypt these data with your (say AES) key number 1". A typical SIM card will have no command for it.
You have to collect the use cases you are interested in by yourself. Some ideas:
encrypt these data
decrypt this cryptogram
compute or verify this message authentication ocde
derive session key
replace key data of existing key
I study the construction of mobile networks and began to study MVAS. But could not find a specific iinformation what protocols are used in the VAS or MVAS.
I understood that main protocol using SMS - it SMPP.
It would be great if someone made a list of the protocols used, or links where I could read more information about the protocols used.
There is such a list; it is published by 3GPP in specification TS 23.039.
3GPP (earlier ETSI) specified the GSM, UMTS and LTE systems, with standard protocols for most of the interfaces. They did not specify any standard protocol between Short Message Service Centres and external messaging servers though.
Instead, this was left open, and each SMSC developer specified their own protocol. An early and successful SMSC developer was an Irish company called Aldiscon, which was later taken over by Logica. They developed the Short Message Peer-to-Peer protocol (SMPP), and published it as an open standard, which is the reason why it's so widely used today.
I'm doing a grad-school software engineering project and I'm looking for the protocol that governs communications between ATMs and bank networks.
I've been googling for quite a while now, and though I'm finding all sorts of interesting information about ATMs, I'm surprised to find that there seems to be no industry standard for high-level communications.
I'm not talking about 3DES or low-level transmission protocols, but something along the lines of an Interface Control Document; something that governs the sequence of events for various transactions: verify credentials, withdrawal, check balance, etc.
Any ideas? Does anything like this even exist?
I can't believe that after all this time the banks and ATM manufacturers are still just making this up as they go.
A shorter question: if I wanted to go into the ATM software manufacturing business, where would I start looking for standards?
Well, there are lots of interbank networks. I would guess that each of them communicate differently. The stickers on the ATM (Cirrus, STAR, Pulse, etc...) identify which network the machine participates in. I do believe, though, that the "structure" of the message is dictated by an ISO standard. Cirrus is a Mastercard owned network and PLUS is a Visa owned network... I'd scour their sites to see if they publish any API details.
Edit, by request:
Have a look at the following ISOs 15022, 20022, 9362 and 4217 -- http://en.wikipedia.org/wiki/Category:Financial_routing_standards
ISO 8583 is dominant.
Also, take a look at EMV.
The ATM to bank link can be proprietary or standard. It is only upstream where inter-organisation wire level interoperability is needed, that standards become always necessary.
ISO 15022 definitely doesn't cover ATM to bank. So far, it covers further upstream. And is now superseded by ISO 20022 - "originally named ISO 15022 2nd edition".
ISO 20022 covers the total scope of financial services, and acts as a super forum for ISO financial services protocols.
There are two basic protocols, ISO8563 and IFX (a financial XML subset) but many banks us protocols supplied by the vendor, because these include Device driver protocols that drive the ATM 'States', There is also a reporting protocol where the ATM reports its cash and usage statii.
